' PLOW ATTACHMENT.

Application filed March 9,1911... Serial in). 613,232.

'Hendrum, in the coon y of Norman and State of l iIlQriIliiQ haveinvented a new and useful Plow Attachmenh of which the following a siecification. I

This invention as relation to plow attachments ll cons in the norelconstruction and 'rangg ement of its parts hereinafter desrgibed andclaimed.

The object of the invention is to provide a plow attachment of simpleand durable lapted to be applied to the beam of a in-ealtin z plow inadi'anrc of the share hntl adapted to operate upon and stir the top s "eson ust berore the inrrow tn, by the 15y such an arrangnrment thestubble or trash at the sin-nice oi the soi ml? with thetop soil. andwhen th iurrow slice is turned the said slice will snugly in the subsoiland air spaces usually found between the furrow vslice and the l/S llwill bereduced in number and ions. llheretorc after the soil has tweeplowed the top soil will he in close contact with the sub-soil whichwill conwrve the moisture in the sub-soil so that it 11m; be tat-:en upby capillary attraction by the top soil.

' in the accompanying drawings: Figure 1 is a top plan view of abreaking); plow with the attaclnuent applied. Fig. 2 a side elevation otthe attachment with parts in section. Fig. is a lL-"itil view of theattachment with parts in section.

As hcreinbcfiare stated theattachment is adzmted to he applied to abreal; plow and as shown in the drawings such a pic consists or a beam 1and a share he attachment is applied to i116 heam 1 just in advance ofthe share 2 in arm 3 is adapted .tobe secnr'ed to the side of the beam 1by a suitable clamp device as that illustrated at 4-. The arm 3 isformed with its end nortions at a right angle to each other the upperend portion of the said arm being located in a lane midway between theends of the lower portion of the arm. The part of the said arm betwe theupper and lower extremities thereof bent or bowed to one. side as at 4*,firsap is fixed to the. lower po on of the arm 3 and a washer 6 of softmetal is mounted open the lower portion of the arm against one of thefaces of the stop Specification of Letters Patent.

A sleeve 7 is journal ed upon the lowerportion of the arm 3 and one endbearsagainst the face of the washer A pin 8 is passed transverselythrough the outer end portion of the lower part of the arm 3- and servesas means for holding the sleeve 7 upon the said portion 01" the saicarm. A nut 9 is screwed upon the innerend of the sleeve"? and issurrounded by a jacket which also surrounds the stop 5 and washer, (3.Stop plates 10 and 11- are fixed to the intermediate portions oft-hesleeve 7 and are. spaced from each other A gang of disks and 13 ismounted upon the sleeve 7 and these disks bear against the sides ofthestops 10 and 11 respectively. A washer plate 14 is interposed betweenthe jacket 5 and the disk 12 and the said nut serves as means forclan'iping the disk 12 between the plates 10 and 14. A washer plate 15bears against the outer face of the disk 13 and a nut 16 screwed uponthe outer end of the sleeve 7 serves as means for clamping the disk 13between the plates 11' and 15. A cap 16 is screwed upon the outer end ofthe sleeve 7 and incloses the pin 8 and the extremity of the lower endportion of the arm 3. JV hen the attachment is applied to a plow thelower portion of the arm 3 is disposed at an angleto the loi'igitudinaldimension of the plow beam 1 and. to the line of draft of the plow andthe lower edges of the disks 12 and 13 are at a higher elevation thanthe edge ofthe share-2. Consequently the disks 12 will operate in thetop soil in advance of the share 2 and inasmuch as the edges of the saiddisks will lie in planes at an angle to the lineofi draft the said diskswill rotate and cut the material atthe top soil. By reason of the factthat the lower portion of the arm 3 and the disks carried thereby are(llbPOSQCl. as indicated. there will be thrust strain along the sleeve 7but the said. sleeve will have its rear end bearing against the softmetal washer 6 located against the face of the stop 5 and therefore itwill be braced in its position upon the lower portion of the an 3. Thecap 16 will prevent the entrance of sand or other foreign material between. the sleeve and that portion of the arm 3 upon which it isjournalcd.

It will h? apparent, by referring to Fig. that the disks 12 and 13 arelocated at opposite sides of: the longitudinal axis of the. iippei' endportion 3 so ti it, when the device is in nee the pressure against thedisks will and the tendency of the attachment to twist or turn is thusreduced to the minimum.

As a result, very simple means can be utilized for attaching the deviceto the beam 1 as it is' not necessary to provide any special type offastening to prevent twisting or rotation of the part 3.

Having described the invention what I claim as new and desire to secureby'Letters Patent is:

A plow attachment including an arm, a stop thereon, a sleeve mounted forrotation upon the arm, stop plates fixed on the sleeve, disks on'thesleeve between the stop plates and the respective ends of the sleeve,washer plates interposed between the disks and the adjacent ends of thesleeve, nuts engaging the ends of the sleeve for binding the washerplates upon the disks and binding said disks 7 arm for holding thesleeve against said wear device, a cap detachably engaging the sleevefor housing said holding means, and a jacket engaging the stop andextending around the nut on one end of the sleeve.

' In testimony that I claim the foregoing as my own, I have heretoafiixed my signature inthe presence oi: two witnesses.
